WATER-MOTOR.

SPECIFLCEATION forming part of Letters Patent No. 1764,403, dated July 5, 1904.

Application filed July 23, 1908. Serial No. 166,718. (No model.)

To all whom it may concern.-

Be it known that I, Moses H. WHITE, a citizen of the United States, and a resident of Everett, in the county of Snohomish and State of- Washington, have invented a new and Improved Water-Vlotor, of which the following is a full, clear, and exact description.

This invention relates to a water-motor intended particularly to operate a pump or )0 umps for elevating the water of a stream; but it is applicable to other purposes, as will be apparent.

As here illustrated, the apparatus com.- prises a casing open at each end and having a flat base on which it may rest in upright position on the bed of a stream, so that the water flows through the casing. Placed longitudinally in the casing is a peculiarly-constructed screw, the plates of which are acted on by the current, whereby a rotary movement is imparted, and said movement is utilized for operating the pumps which are attached to the casing and by which the water is elevated.

The invention is particularly useful for the elevation of water to be used for irrigating purposes.

This specification is an exact description of one example of the invention, while the claims 3 define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specifieation, in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is a front elevation of the invention with one of the pumps broken away, and Fig. 2 is a longitudinal section of the invention.

The casing a may be constructed of any 4 suitable material, preferably in whole or in part of iron, so that it will have the necessary weight to rest on the bed of the stream and resist the current movement. The base a of the casing is formed flat, as shown, thus enabling the apparatus to maintain its upright position. At each end of the casing is arranged a spider I), and in these spiders is mounted the central longitudinal shaft 0.

- the pump-cylinders.

Said shaft has spokes a fastened thereto at each end inside of the respective spiders I), 5 and these spokes carry the hollow cylindrical hub of the screw. Said hub is open throughout its length, as shown, and in this way the resistance of the hub to the current striking it is reduced to the minimum degree, and at 5 5 the same time the blades of the screw are removed as far as possible from the center of the hub, and thereby the power of the screw is increased.

f indicates the blades of the screw, which are fastened to the hub a and turn spirally around the same. These blades may be of any desired number. Within the casing, at the bottom thereof, I provide a verticallydisposed baffle g, which extends longitudi- 5 nally of the casing and projects upward to the peripheral line of the screw, this battle preventing the water from assuming a rotary or spiral movement within the casing, and thus increasing the efliciency of the motor. 7 If desired, a plurality of these bafiies may be provided at various points around the inner circumference of the casing.

At one end, preferably the rear end, of the shaft 0 a crank his formed, and to this crank are joined the connecting-rods e of the pumps 7c. The connecting-rods are in turn attached to the piston-rods Z, and said rods carry crossheads on, sliding on guide-rods a, attached to Pipes 0 pass from the respective cylinders upward and are held in place by suitable fastenings a, attached to the casing, said pipes 0 joining at the main discharge-pipe p, through which the water is passed by the action of the pumps. 8 5

In the use of the invention it is preferred to lower the apparatus into the stream by means of derricks or otherwise until the easing is rested on the bottom. Then by securing the device in'this position by means of 9 cables or otherwise its operation will be continuous as long as the current flows. It is not essential, however, that the apparatus be sunk to the bed of the stream, since itinay be used on floats or in sluiees with equally good results.

Various changes in the form, proportions, and minor details of my invention may be resorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as maylie within the intent of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A water-motor, comprising a casing open at each end, a screw extending longitudinally through the casing and. adapted to be actuated by the water-current flowing therethrough, means for revolubly mounting the screw, means for transmitting the movement thereof, and a longitudinally-disposed bafitle lying between the inner wall of the casing and the screw.

2. A water-motor, comprising a casing open at each end, a hollow hubopen throughout its length, for the purpose specified, means for mounting the same revolubly in the casing, a spiral blade attached to the hub, and means for transmitting the movement of the hub.

3. A water-motor, comprising a casing, a spider in each end thereof, a shaft mounted to turn in. the spiders, a hollow hub attached to the shaft and open at each end, a spiral blade attached to the hub, and means for transmitting the movement of the hub.

4:. A water-motor, comprising a hollow cy lindrical hub open at each end, means for revolubly mounting the same, a spiral blade attached to the exterior of the hub, and means for transmitting the movement of the hub.

5. A water-motor, comprisingacasing open at each end, a spider mounted in each end of the casing, a shaft revolubly mounted in the spiders and having a crank at one end thereof, a hollow hub mounted on the shaft, a spiral blade attached to the hub, a connecting-rod attached to the crank, and a pump, the mobile pagt of which is attached to the connectingro In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. 1
